OUTLET-VALVE AND VALVE-SEAT FOR OIL-CANS.

SPECIFICATION forming part of Letters Patent No. 509,411, dated November28, 1893.

Application filed January 5, 1893. Serial No. 57,323. (N0 model.)

To all whom it may concern.-

Be it known that I, ALBERT H. WALKER, of Brooklyn, county of Kings, andState of New York, have invented a certain new and useful Improvement inOutlet-Valves and Valve- Seats for Oil-Cans, of which the following is aspecification.

This invention relates to outlet valves and valve seats for canscontaining illuminating oil, orthe like, the object being to provide asimple valve and faucet which may be easily attached to or detached froma can and which will occupy the minimum of space above the can top aswell as afford surety against leakage in transportation.

I will describea practical embodiment of my improvement, and then pointout the novel features in the claim.

In the accompanying drawings, Figure 1 is a top view of a corner portionof a can, with a valve seat and socket secured thereto and embodying myimprovement. Fig. 2 is a transverse vertical section thereof. Fig. 3 isa section of the same parts enlarged with the valve cover and spout inposition. Fig. 4 is a top or plan view thereof. Fig. 5 is a sectionshowing a modification.

Referring by letter to the drawings A designates a portion of the top ofa can, and A is the socket secured thereto and carrying the valve seatand seal A This socket is made of sheet metal and when secured in placeextends toward the interior of the can so that the valve seat is locatedsome distance below the plane of the top A and the seal immediatelybelow the seat. A screw threaded portion a extends upward from the valveseat and the upper end of the portion a has an outwardly extendingannular flange a, the edge of which is designed to be soldered to thetop A. To prevent the solder from running into the valve seat during theprocess of soldering I may provide a dam on the upper surface of theflange a. This dam consists of an upwardly extending annular bead a onthe flange (1/. Ordinary care, however, in applying the solder willrender such a dam unnecessary and I propose generally to omit it. Theflange a may have a small radial rib or stud a which in conjunction witha similar mark on the top A as seen in Fig. 1

will indicate the properposition in which the valve seat is to be set sothat its threaded portion will properly receive the threaded portion towhich the outlet spout and cap are attached and so as to direct thespout outward when the parts are screwed up. The seal consists of a pluga removably secured to the opening through the valve seat. It ispreferably in the form of a disk of metal soldered to the edge of theopening and may be readily punched out to provide communication with theinterior of the can. The seal is left intact when the can is to beshipped, thus insuring absolute protection against leakage, even if thecover should be knocked off or broken.

B designates a valve having a screw threaded stem 1) extending upwardthroughacap or cover B. An internally screw threaded nut l) is securedto the inner side of the cap or cover 13' and the stem 1) is engagedwith this nut. The upper end of the stem is provided with a hand piece0. The cap or cover B has a downwardly extended screw threaded flange bto engage the threaded portion a of the socket. In Fig.3 I have shownthe cover B as having its edge projected overthe flange a of the socket,but this is not essential and is omitted in Fig. 5. A spout B extendsoutward from the cap or cover B, and the cover has a vent 12 In Fig. 3the valve B is shown as a disk of cork or similar yielding materialsecured to the stem 1) by means of a metal shell b and in this examplethe valve seat proper is formed by a wall (L5 inclined inward anddownward. The edge of the valve B will bear closely on this inclinedseat and form a tight joint.

In Fig. 5 the valve is shown as a disk of metal secured to the valvestem, and the valve seat in this example consists of a ring 0 of cork orsimilar yielding material. In this example the fiange b of the cover hasan inwardly turned annular flange 0 adapted to bear upon the valve seat.

My invention is designed more particularly to he used on what is knownas wire handle cans which are packed for exportation in what is known asa low case. In any style of can, by sinking the valve seat and sealbelow the top of the can, a case for packing the cans can be made muchlower than is possible with any style of can in which the valve seatextends above the top of the can. This difference in space makes aconsiderable difierence in transportation rates and the practical valueof my invention is thereby materially enhanced.

Having described my invention, what I claim is An oil can comprising abody portion,a sheet metal screw threaded socket extending down into thesame so as to be below the plane of the can top and provided with avalve seat,'having a sealed portion of thin metal secured to theopposite side and below the valve seat, a screw threaded cap or plugengaging with the interior of the same,

wholly above the valve seat and having a transversely extending spoutarranged upon its top-portion, a valve co-actingwith said valve seat,and a screw fitted to said cap or plug and attached to the valve,substantially as specified, whereby a plug or cap provided with a spoutand a valve actuating device, of but slight projection above the top ofa can, is afforded and the valve is made to protect not only the valveseat, but also the joint between the cap or plug and the socket.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

ALBERT H. WALKER.
